Proper Use of Microban for Mold

Catherine Chase

Microban cleaning formulas kill microorganisms such as harmful bacteria and viruses and should be applied carefully.

Cleaning away mold can reduce the risk of respiratory problems.

Originally developed for use as disinfectants in hospitals, Microban cleaning formulas kill microorganisms such as harmful bacteria and viruses. As effective agents against fungi, mildew and mold, Microban formulas provide an alternative solution to chlorine bleach. These water based formulas are pH balanced and noncorrosive. The Microban Germicidal Cleaner Concentrate is appropriate for hard, nonporous surfaces, while the Microban Disinfectant Spray works on both porous and nonporous surfaces.


When cleaning areas such as attics, crawl spaces and basements, the spray can be used on animal carcasses and waste prior to removal.


Work in a well ventilated area, opening windows or air vents whenever possible. Wear latex gloves and a face mask when applying chemicals and especially when dealing with mold.

Germicidal Cleaner Concentrate

  1. Pour 1 gallon of water into a bucket.

  2. Add 2 oz. of Microban Germicidal Cleaner Concentrate to the bucket.

  3. Mix the solution with a clean paint stick or similar item.

  4. Dip a sponge or mop into the solution, depending on your specific cleaning needs. Thoroughly drench the affected area and scrub as needed. Allow the surface to stay wet for 10 minutes.

  5. Allow the area to dry.

Disinfectant Spray

  1. Pre-clean the area with a sponge and an all-purpose cleaning spray to remove dirt or debris. Pre-clean fabrics with a suitable detergent. Test the spray in a hidden area before using on entire item.

  2. Spray the area with Microban Disinfectant Spray until it is thoroughly saturated. Drench the area enough so that it is still wet after 10 minutes.

  3. Wipe the area with a sponge, if necessary, to remove the mold spores. Use a sponge on fabrics with tight weaves to help work the product in. Re-spray the area and allow it to dry.
